Patent 197.257, and April (5, 1921, application301/1369: Belgium, March 31. 1921, Patent 295.2621, and April 5, 1921,Patent 295,526, and of which the following is a specification.

This invention relates to lace braiding machines and more particularlyto so called one thread lace braiding machines, comprising as manybobbin carriers as carrier drivers.

The invention relates further particularly to such machines whosedrivers are each rotatable clockwise and counter-clockwise.

One feature of the invention consists therein that the race plate havingintersecting race openings arranged on a curve shows for each opening amember leaving race way portions between itself and the plate and apartfrom these members rotatable and arrestable carriers adapted to guidewhen arrested. the carriers past the outer and inner points formed inthe race way plate by the said intersecting race openings.

Another feature of the invention consists in arranging the drivers atequal levels in such a way that the moving drivers can pass stationaryneighboring drivers. This is accomplished by providing the carriers withdriven parts that are of such thickness that the guiding parts of thestationary drivers guide the carriers past the pointed sections of thetrack even though the guiding portions of the drivers recede from thetrack.

Another feature consists therein that from the rack wheels adapted torotate the drivers each clockwise and counter-clockwise the rack wheelnearest to the driver and surrounding the driver shaft is arranged on asleeve also surrounding the driver shaft and stationarily arranged inthe machine.

Still another feature consists in limiting the motion of the couplingmeans in such a manner that the springs tending to return the couplingmeans against the pull of a jacquard apparatus are not able to move thecoupling means beyond a certain rest position.

A constructional form of the invention is illustrated in the drawing,

Fig. 1 being a plan view of a track plate with the bottom driversbeneath it,

Fig. 2 is a section on the line A.B of Fig. 1,

Fig. 3 an elevation of two adjacent operating devices for the driverslooking in the direction of the arrow in Fig. 2, the external parts ofthe one driving device being broken away.

Fig. l is a perspective view of a part of the track plate with thedrivers beneath it.

Referring to the drawing a a a at rep resent four successive driversWhose axis are intersected by a circle If, These drivers are arranged atequal heights as will be seen in Fig. 3. The shape of the drivers issuch that the rotating drivers a a can move past the stationary driversa a without striking against their edges. The points (Z of the outeredge of the track are further away from the circle than the points a ofthe inner edge of the track. The result obtained by this arrangement isthat, even though the drivers are arranged in a curve or circle 6 sothat the outer sections of the symmetrical drivers 0 a are further apartthan their inner sections, the drivers will nevertheless guide thecarriers past the points of the pointed sections of the track in aproper manner with the aid of disks f attached to the foot end of, thecarriers 0. It will be seen from Fig. 1 that the distance a; between theinner portions of the drivers a and a is shorter than the distance ybetween the outer portions of the same drivers. The guide members 7' aredisposed on a different circle. 6 from that of the driversv cular in Thestarting and stopping of the drivers is accomplished in the followingmanner:

When a rod operated by ajacquard apparatus is pulled in ti c directionof one of the arrows shown in Fig. 2 the rod 9 is either raised orlowered. When the rod 9 is lowered the teeth oi the coupling member hare thrown into engagement with the clutch of the toothed Wheel 2'. Thecoupling member '/i is a ranged to move up and down but not to rotate onthe sleeve is. Assuming that the toothed wheel 71 rotates clockwise. thedriver a will be moved clockwise by the sleeve 7? when the couplingmember h is thrown into gear with toothed wheel 2'. A disk Z is mountedon the sleeve so as to rotate with it. The disk Z has notches m intowhich a detent a, which may be rigidly fixed to the coupling fork 0, attimes protrudes. When the rod 9 is moved the detent it leaves thenotches and wipes over the top or bottom surface or" the disk Z. Theupward movement of the rod 5/ coinpresses a spring 7) and another spring9 mounted on the rod "opposite the said spring remains inactive. Theretrograde movement of the rod in either direction is controlled bymeans oi pins 7* fixed to bars a and cross members i strike against thepins thuspositioning the coupling fork and its detent in a predeterminedposition preterably at the central portion of the rod. When the jacquardapparatus ceases to operate the coupling member is maintained inengagement with the particular clutch until the 'detent a appears aboveor below a notch m in the disk Z thereby snapping into ongagement withthe notch by the expansion of one of the springs hence the couplingmember will be thrown out of gear and the disk Z leaves the driver of,in its stationary position in which it acts as a guide member. Thetoothed wheel it turns to the left while the toothed wheel 2' turns tothe right, so that when the rod 9 is pulled down cansin the couplingmember h to engage with he driver a? will be rotated to the left. Thetoothed wheel, 2' is iournalled on a fixed sleeve or hollow shaft 4) inorder to prevent the driver from being caused to execute undesiredrotary motion by the constantly rotating toothed wheel 2'. The toothedwheel a may e supported by a supmember '20 n: (.b may be semi cirshapeand attached to upright Tl'io drivers y also be enabled to pass eachother b some or all of them being arranged "in different levels.

In such cases the drivers may be made broader and the disk 7 may bedispensed with. But in accordance with the invention the points oi? thepointed sections of the outer 'edge of the boibin track will then alsohave to be further iirom the circle 7 than the points 0? the inner edgeof the said track.
